Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687208, here are decompositions:

11 + 8687197 = 8687208
37 + 8687171 = 8687208
59 + 8687149 = 8687208
67 + 8687141 = 8687208
139 + 8687069 = 8687208
181 + 8687027 = 8687208
227 + 8686981 = 8687208
307 + 8686901 = 8687208

Showing the first eight; more decompositions exist.
